Abstract: Precise managed pressure drilling (MPD) technology is a key technology to ensure the safe drilling in narrow safety density window formations and pressure-sensitive formations. The technology and equipment are mature abroad, but the service price is rather high. The prototype research was completed during the nation’s 11th Five-Year Plan Period, but the prototype was not brought under field test nor put into industrialized application. To push on its localization and industrialization, so as to solve similar drilling problems in strategic oil/gas fields in Tarim, Sichuan and Chongqing, China National Petroleum Corporation has set up a project for field test of precise MPD technology and equipment. Through top-design of “4511” targets, reasonable effective project organization, strengthened nodal control, and strict process monitoring, the complete set of MPD technology and equipment is configured, a stride from the engineering prototype to commercial application of MPD is realized, and a fast lane for the conversion of MPD innovation into production forces is built. This MPD technology and equipment has been widely used in Sichuan and Chongqing, Jidong, Tarim and overseas blocks to support the petroleum exploration and development, resulted in remarkable economic efficiencies. It has embodied CNPC innovation capacity, hoisted CNPC engineering technology to a new level and enhanced CNPC competitiveness at overseas markets.
